From the previous study of electromagnetic radiation in Physics, we learned
that color is related to the frequency (or wavelength) of light. Yet color is
also related to temperature. For instance, by observing colors of the stars, we
could tell which stars are hotter and which ones are cooler.

Since all objects are made up of atoms, which vibrate when thermal energy
is received from an outside source. The greater the thermal energy received,
the
more vigorously the atoms vibrate. If the atoms are vibrating fast enough, it
may emit light. Cooler objects emit primarily low frequency waves, while warmer
objects emit waves with primarily higher frequencies. Therefore, objects at higher
temperatures emit waves of high enough frequency to be visible and we start
to
see red colored objects, also known as "red hot" objects. If the temperature
of an object continues to rise, the emitted wavelengths become even higher in
frequency, and the observed color becomes orange or yellow. At even higher temperatures,
the amount of visible light emitted by the object covers the entire visible
spectrum
about equally and our eyes see it as white. This is what is known as a "white
hot" object.

According to my research, no matter what kind of materials an object is made
of, it will glow white when its temperature is in the range of 1,500 to 11,000 K.
